Issue
In the past, opening a logout dialog while a shutdown dialog is shown and vice versa closed the old dialog and opened the new one. Now, opening a logout dialog while a shutdown dialog is active and vice versa results in nothing happening.

Steps to reproduce
Click shutdown in menu. Then click logout. See that you still have the shutdown dialog and not the logout one.

Expected behaviour
Opening a logout dialog while a shutdown dialog is opened should result in that being closed and a logout one being shown. And vice versa.
